Allow extraction of formula output in an input param

[henriquemoraeszup]

What would you like to be added:
We need to be able to execute a formula and use its output as either a list or a scalar value from another formula input. Example

{
   "name": "rit_my_out_val",
   "type": "output",
   "output": {
       "command": "rit aws buckets list --region=us-east-1",
       "name": "my_bucket",
       "type": "list|multi|text|bool"
   },
}

Why is this needed:
To enable a more robust use of dynamic inputs implementation
